epilarynx

The epilarynx is a poorly defined anatomical region located at the supraglottic larynx, superior to the ventricular folds and extending to the hyoid bone. It is not a distinct anatomical structure with clear boundaries but rather a functional or conceptual area involved in vocalization and airway protection. This region includes several anatomical components such as the epiglottis, aryepiglottic folds, and the false vocal cords (ventricular folds).

Functionally, the epilarynx plays a role in modifying the resonance of the voice. The shape and size of the epilaryngeal cavity can influence the timbre and quality of sound produced by the vocal cords. It is also intimately involved in the complex mechanisms of swallowing, where its structures help to seal off the airway and prevent food or liquid from entering the trachea. During phonation, the epilarynx can be adjusted to alter vocal characteristics, and it is a significant area of focus in voice training for singers and actors aiming to achieve specific vocal effects.

Research into the precise anatomical delineation and functional contribution of the epilarynx continues. Understanding its role is crucial for diagnosing and treating certain voice disorders and for developing effective therapeutic interventions. Its involvement in both vocal production and airway defense highlights its importance in the overall physiology of the upper airway.
